TL;DR: The KADS methodology is described to show how structured knowledge engineering of a problem can be based on documented techniques for project management, analysis, and design, however, such techniques still result in the development of independent systems in isolated domains and do not optimise the re-use of general knowledge.

Abstract: Knowledge Engineering is the aspect of systems engineering which addresses uncertain process requirements by emphasising the acquisition of knowledge about a process and representing this knowledge in a Knowledge Based System. The discipline has moved from one producing small expert systems to one producing embedded KBS in larger computational solutions. This transition has resulted in the development of methodologies that guide the knowledge engineering of a product. The KADS methodology is described to show how structured knowledge engineering of a problem can be based on documented techniques for project management, analysis, and design. However, such techniques still result in the development of independent systems in isolated domains and do not optimise the re-use of general knowledge. The CYC project to represent a portable set of general knowledge that can be used as a basis for any novel system is described. MMI 2 is the third project described which addresses the engineering of knowledge about communication itself, rather than a discrete problem domain, into the interface of computer systems to improve the interaction with the user, as well as the solving of domain problems.

TL;DR: The comparison of the predicted values with analytical ones indicates the potential of using ANNs for the prediction of the fundamental period of infilled RC frame structures taking into account the crucial parameters that influence its value.
Human–robot interaction in agriculture: A survey and current challenges
TL;DR: This work surveys HRI approaches andications focused on improving the working conditions, agility, efficiency, safety, productivity and profitability of agricultural processes, in cases where manual labour cannot be replaced by but can be complemented with robots.

Distributed neural dynamics algorithms for optimization of large steel structures
Hyo Seon Park,Hojjat Adeli +1 more
TL;DR: In this paper, distributed nonlinear neural dynamics algorithms for discrete optimization of large steel structures are implemented on a recently introduced distributed memory machine, the CRAY T3D, and applied to the minimum weight design of three large space steel structures ranging in size from 1,310 to 8,904 members.

TL;DR: In this article, sediment is either loaded as bed-load with particles sliding, saltating, and rolling over the river bed, or as a suspended-load, where particles move with the turbulent water flow away from the bed.

A translation approach to portable ontology specifications
TL;DR: This paper describes a mechanism for defining ontologies that are portable over representation systems, basing Ontolingua itself on an ontology of domain-independent, representational idioms.

Toward principles for the design of ontologies used for knowledge sharing
TL;DR: The role of ontology in supporting knowledge sharing activities is described, and a set of criteria to guide the development of ontologies for these purposes are presented, and it is shown how these criteria are applied in case studies from the design ofOntologies for engineering mathematics and bibliographic data.

Maintaining knowledge about temporal intervals
TL;DR: An interval-based temporal logic is introduced, together with a computationally effective reasoning algorithm based on constraint propagation, which is notable in offering a delicate balance between space and time.
